Generation of Love Wave in a Media with Temperature Dependent Properties Over a Heterogeneous Substratum

The present paper deals with the generation of Love waves in a layer of finite thickness over an initially stressed heterogeneous semiinfinite media. The rigidity and density of the layer are functions of temperature, i.e. they are temperature dependent.  The lower substratum is an initially stressed medium and its rigidity and density vary linearly with the depth. The frequency relation of Love waves has been acquired in compact form. Numerical calculations are accomplished and a number of graphs for nondimensional phase velocity versus nondimensional wave number are plotted to display the influence of intrinsic parameters like initial stress and inhomogeneity factors on the generation of Love waves. It is initiated that the nondimensional phase velocity of Love wave decreases with increase in the nondimensional wave number and is strongly influenced by the initial stress of the substratum and the inhomogeneity factors of the layer and the substratum. This study may provide effective information in the field of industrial engineering, civil engineering as well as geophysics and seismology.
